| RemoveRange | | public class RemoveRange extends Filter implements UnsupervisedFilter,OptionHandler(Code) | |
A filter that removes a given range of instances of a dataset.
Valid options are:
-R <inst1,inst2-inst4,...>
Specifies list of instances to select. First and last
are valid indexes. (required)
-V
Specifies if inverse of selection is to be output.

|
| batchFinished | | public boolean batchFinished()(Code) | | Signify that this batch of input to the filter is
finished. Output() may now be called to retrieve the filtered
instances.
true if there are instances pending output
throws:
IllegalStateException - if no input structure has been defined |
| getCapabilities | | public Capabilities getCapabilities()(Code) | | Returns the Capabilities of this filter.
the capabilities of this object

| getInstancesIndices | | public String getInstancesIndices()(Code) | | Gets ranges of instances selected.
a string containing a comma-separated list of ranges |
| getInvertSelection | | public boolean getInvertSelection()(Code) | | Gets if selection is to be inverted.
true if the selection is to be inverted |
| getOptions | | public String[] getOptions()(Code) | | Gets the current settings of the filter.
an array of strings suitable for passing to setOptions. |
| globalInfo | | public String globalInfo()(Code) | | Returns a string describing this filter
a description of the filter suitable fordisplaying in the GUI. |
| input | | public boolean input(Instance instance)(Code) | | Input an instance for filtering. Filter requires all
training instances be read before producing output.
Parameters:
instance - the input instance true if the filtered instance may now becollected with output().
throws:
IllegalStateException - if no input structure has been defined |
| instancesIndicesTipText | | public String instancesIndicesTipText()(Code) | | Returns the tip text for this property

| invertSelectionTipText | | public String invertSelectionTipText()(Code) | | Returns the tip text for this property
tip text for this property suitable fordisplaying in the explorer/experimenter gui |
| listOptions | | public Enumeration listOptions()(Code) | | Returns an enumeration describing the available options.
an enumeration of all the available options. |
| main | | public static void main(String[] argv)(Code) | | Main method for testing this class.
Parameters:
argv - should contain arguments to the filter: use -h for help |
| setInputFormat | | public boolean setInputFormat(Instances instanceInfo) throws Exception(Code) | | Sets the format of the input instances.
Parameters:
instanceInfo - an Instances object containing the input instancestructure (any instances contained in the object are ignored - only thestructure is required). true because outputFormat can be collected immediately
throws:
Exception - if the input format can't be set successfully |
| setInstancesIndices | | public void setInstancesIndices(String rangeList)(Code) | | Sets the ranges of instances to be selected. If provided string
is null, ranges won't be used for selecting instances.
Parameters:
rangeList - a string representing the list of instances. eg: first-3,5,6-last
throws:
IllegalArgumentException - if an invalid range list is supplied |
| setInvertSelection | | public void setInvertSelection(boolean inverse)(Code) | | Sets if selection is to be inverted.
Parameters:
inverse - true if inversion is to be performed |
| setOptions | | public void setOptions(String[] options) throws Exception(Code) | | Parses a given list of options.
Valid options are:
-R <inst1,inst2-inst4,...>
Specifies list of instances to select. First and last
are valid indexes. (required)
-V
Specifies if inverse of selection is to be output.
Parameters:
options - the list of options as an array of string.s
throws:
Exception - if an option is not supported. |
